[JDEV] Jabber Client - Sockets problem

[Glenn MacGregor]

First - You may want to look at some libraries that already do that,
jabberoo (Linux, win32).  JabberCOM (COM based win32) and there are some
java libs as well.

If you need to make your own, you should look at jabberoo for some ideas.

I assume your lib is based on a select (or poll) loop, when select (or poll)
returns with > 0 you need to read (or recv) on the active file
descriptor(s).  Both functions (read or recv) will work for you in linux but
you need to use recv in win32.

So you create a static buffer of whatever size you want (4 or 8k is usually
good).  You pass that to recv which fills it.  Your lib needs to employ a
SAX XML parser which you can pass the recv'd data to.  If the data in the
recv kernel buffer is larger than you can read you will get the rest on the
next time through the select loop, pass it on to the parser.

At that point the lib needs to use some kind of callback mechanism to call
the app that is using the lib.
